MEMS Sensor Spoofing Defense Patent Snapshot 2026
The MEMS sensor spoofing defense field is in an early-growth stage with 9 patent families in scope, dominated almost entirely by Texas Instruments. Activity is expanding on a multi-year basis, though annual volume eased from its 2023 peak and the most recent years carry additional undercount from publication lag.
Texas Instruments holds commanding lead in a nascent field
Texas Instruments is the clear leader, holding the top position in applicant rankings. The University of Michigan and the Council of Scientific and Industrial Research each hold smaller positions, making the field highly concentrated at the top.
The top five filers account for 100% of the ranked applicants visible in this query’ combined total, signaling an extremely tight visible assignee structure with virtually no mid-tier challengers yet established.

|---|---|---|---|
| 1 | Texas Instruments Incorporated | 8 | |
| 2 | Regents of the University of Michigan | 2 | |
| 3 | COUNCIL OF SCI & IND RES | 1 |
Texas Instruments’ commanding position implies it has set foundational technical directions in this space; new entrants will need to differentiate around adjacent or complementary approaches to avoid direct overlap.
The most recent 18–24 months of filing data are likely under-represented due to standard patent publication lag; the apparent drop in 2024–2026 should not be interpreted as declining interest. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Multi-year growth with navigation and inertial sensing at the core
Annual filings show a field that has grown meaningfully since 2017, with a notable cluster around 2022–2023; the technology mix is anchored by inertial and navigation sensing classes, with digital processing playing a secondary but material role.
Annual filing trend
Filings were sporadic from 2017 through 2021, then accelerated to a 2023 peak of 3 records before dropping in 2024–2026 — a pattern consistent with publication lag rather than a genuine reversal. The 150% recent-window growth rate confirms the multi-year expansion remains intact.

G01P (velocity and acceleration) is the visible branch, followed closely by G01C (navigation and gyroscopes) and G06F (digital data processing), reflecting that spoofing defenses rely heavily on inertial signal validation and algorithmic detection. Medical (A61B) and automotive steering (B62D) each appear at the margins, indicating early but limited cross-sector reach.

Protecting motion sensors from acoustic injection …
Cyber-physical systems depend on sensors to make automated decisions. Resonant acoustic injection attacks are already known to cause malfunctions by disabling MEMS-based gyroscopes. However, an open question remains on how to move beyond denial of service attacks to achieve full adversarial control of sensor outputs. This work investigates how analog… (excerpt from the patent abstract)

Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Texas Instruments
Texas Instruments holds 8 patent records and focuses on navigation and gyroscope sensing (G01C 21, G01C 22) alongside velocity and acceleration measurement (G01P 15), indicating a defense strategy built around validating inertial navigation outputs. Momentum data classifies the company as a new entrant in recent filings, consistent with a deliberate, recent build-out of this portfolio rather than a long-standing effort.
patent records: 8University of Michigan (Regents)
The University of Michigan holds 2 patent records with technology emphasis in velocity and acceleration measurement (G01P 13, G01P 15), suggesting foundational research into detecting anomalous inertial signals. As an academic actor, its patents may represent licensing opportunities or technology-transfer pathways for industrial players seeking to broaden their defensive coverage.
patent records: 2Frequently asked questions
The corpus contains 9 patent families in scope. This is a small but growing body of IP concentrated in the United States.
Texas Instruments is the visible filer, holding 8 patent records — far ahead of the next-ranked applicants, the University of Michigan with 2 and the Council of Scientific and Industrial Research with 1.
The field is classified as Growth. Recent three-year filings are 150% above the prior three-year window on a multi-year basis, though annual volume eased from its 2023 peak and the most recent years carry additional undercount from publication lag.
G01P (velocity and acceleration measurement) is the most represented branch, followed by G01C (navigation and gyroscopes) and G06F (electric digital data processing). These three branches reflect the core inertial-signal validation approach most commonly used in spoofing defenses.
Yes. The United States is the visible filing jurisdiction, with India as the only other jurisdiction represented. Europe, China, Japan, and South Korea are absent from the current corpus, representing both exposure for existing assignees and an opening for non-U.S. filers.
Medical diagnosis (A61B) and automotive steering systems (B62D) each account for just 1 patent record, or roughly 3% of the corpus each. Both represent plausible extension contexts for existing inertial spoofing defense techniques, though neither has attracted significant filer attention yet.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
